When it comes to investing in solar panels, one of the most common questions asked is which type is better: mono or poly? While the answer is not straightforward, it depends on various factors, including the location, budget, energy needs, and more.
Firstly, let’s define what mono and poly solar panels are. Mono panels are made from a single crystalline silicon cell, while poly panels are made from multiple silicon cells melted together. The differences between the two types of panels can impact their efficiency, durability, and cost.
Efficiency
Mono solar panels are known for their higher efficiency levels compared to poly panels. The reason for this is that mono panels have a higher purity of silicon, which means they can convert sunlight into electricity more efficiently. On average, mono panels have an efficiency rating of around 20%, while poly panels have an efficiency rating of around 15-17%.
However, it’s worth noting that the difference in efficiency is not significant enough to make a massive impact on the overall energy production of a solar panel system. In other words, if you have a limited budget, you can still opt for poly panels without sacrificing much in terms of energy output.
Durability
When it comes to durability, both mono and poly solar panels are quite sturdy and can last for several decades. However, mono panels are slightly more durable than poly panels, mainly because they have a simpler design with fewer components. This means that they are less prone to wear and tear and have a longer lifespan.
Cost
Finally, the cost is a significant factor to consider when choosing between mono and poly solar panels. Mono panels are generally more expensive than poly panels, primarily due to their higher efficiency levels. However, the price difference is not significant enough to make mono panels unaffordable for those with a limited budget.
Which is best for the UK?
So which type of solar panel is best for the UK specifically? The answer depends on several factors, including the location, energy needs, and budget.
In general, mono panels are a good option for areas with limited space or where the weather conditions are not ideal for solar energy production. This is because mono panels have a higher efficiency level, which means they can produce more energy from a smaller area. Additionally, mono panels are slightly more durable than poly panels, making them a good choice for areas with harsh weather conditions.
However, if you have a larger roof area and can afford to install more solar panels, poly panels can be a cost-effective option. Poly panels have a lower efficiency level but are generally more affordable than mono panels, making them a good choice for those on a tight budget.
Ultimately, the decision between mono and poly solar panels comes down to personal preferences and priorities. If you’re looking for the most efficient and durable option, mono panels are likely your best choice. However, if you’re looking for a more cost-effective option that can still produce a decent amount of energy, poly panels can be a good choice.
